I am a political scientist with research interests in comparative
politics, political behaviour, and political methodology. In the first
two areas I focus on electoral behaviour, political attitudes and
behaviour in Germany, the relation between social structure and
politics, and on political knowledge and political sophistication. My
methodological research interests focus on the spatial modelling of
party manifestos, survey research methodology in general, computational
statistics and ecological inference. On these topics I have published a
monograph, a variety of book chapters as well as research articles in
Acta Politica, Electoral Studies, the European Journal of Political
Research, German Politics, Perspectives on Politics, and Political
Analysis.

On this website you will find links to publications
and working papers that emerged from these research interests. You will
also find some add-on packages I wrote for
R , the excellent open-source software
package and programming language for data analysis and graphics.
